Which of the following statements is not correct?a)5% aqueous solution...
C) Molecular mass of acetic acid and benzoic acid is higher than normal mass in cryoscopic methods

In cryoscopic methods, the molecular mass of a solute is determined by measuring the depression in freezing point of a solvent. The correct statement would be that the molecular mass of acetic acid and benzoic acid is lower than the normal mass in cryoscopic methods, as they are both molecular compounds and do not dissociate into ions in solution.
